Dental composition for relieving dentin hypersensitivity

摘要

There is provided a dental composition for relieving dentin hypersensitivity comprising (A) an aqueous emulsion component which contains, as emulsion particles, polymer particles having a diameter smaller than that of a dentinal tubule and forming an agglomerate larger than the diameter of a dentinal tubule when they react with a calcium compound, and (B) a water-soluble organic acid component or a water-soluble salt component thereof, a calcium salt of the organic acid being insoluble or hardly soluble in water. Using this composition, dentinal tubules open to the surface of dentin are occluded to relieve dentin hypersensitivity immediately and lastingly.
